CDO

Hello,

When I try to convert a grib file from the DWD opendata repository via remap using CDO-2.2.x, I get the following error:

cdo    remap (Abort): NetCDF: Invalid dimension ID or name

Any hints on how to resolve this issue? I compiled CDO-2.2.2 from scratch but got the same issue. However, the issue is not present when using CDO-2.1.x (which is part of debian:bookworm).

Steps to reproduce on a Linux machine with docker installed:

docker run -it debian:trixie

# The following commands are run inside the container

apt update && apt install -y cdo wget tar bzip2 libnetcdf-dev

export ECCODES_DEFINITION_PATH=definitions.edzw-2.28.0-1
DWD_ICON_TARGET="ICON_D2_002_EASY/target_grid_icon_d2_002.txt" 
DWD_ICON_WEIGHTS="ICON_D2_002_EASY/weights_icon_d2_002.nc" 

if ! [ -e "ICON_D2_002_EASY" ]; then
    wget "https://opendata.dwd.de/weather/lib/cdo/ICON_D2_002_EASY.tar.bz2" 
    tar -xf "ICON_D2_002_EASY.tar.bz2" 
fi

if ! [ -e "$ECCODES_DEFINITION_PATH" ]; then
    wget "https://opendata.dwd.de/weather/lib/grib/eccodes_${ECCODES_DEFINITION_PATH}.tar.bz2" 
    tar -xf "eccodes_${ECCODES_DEFINITION_PATH}.tar.bz2" 
fi

fn="icon-d2-eps_germany_icosahedral_single-level_$(date +%Y%m%d)00_001_2d_t_2m.grib2" 

if ! [ -e "$fn" ]; then
    wget https://opendata.dwd.de/weather/nwp/icon-d2-eps/grib/00/t_2m/$fn.bz2
    bunzip2 $fn.bz2
fi

cdo -f grb2 -remap,$DWD_ICON_TARGET,$DWD_ICON_WEIGHTS "$fn" remapped.grb2
